Description

{TISSUE BIOPSY APPARATUS WITH SEALING FUNCTION}

The present invention relates to a biopsy machine, and more particularly, to a biopsy machine capable of injecting a sealing material into a biopsy area where a biopsy of a target tissue is performed.

A biopsy is a test that detects the presence or spread of disease by removing a part of a living tissue. It is often used for cancer screening or examination for inflammatory diseases.

Currently available tissue biopsy is only for tissue biopsy. There is a possibility of hemorrhage of the biopsy area of the tissue biopsy site. If there is a malignant cell, there is a risk of metastasis to surrounding tissues.

It is difficult to distinguish between malignant uterine sarcoma and uterine myoma. However, it is difficult to distinguish between uterine sarcoma and uterine myoma. It is only possible to do the inspection.

When a biopsy is performed to distinguish between uterine sarcoma and uterine myoma, the uterus belongs to an organ which is likely to be transferred to other organs by blood, In cases of suspected uterine sarcoma, the uterus is often excised because it is assumed to be uterine sarcoma without biopsy. In fact, after uterine removal, it is confirmed that it is not uterine sarcoma, and it is often confirmed that it is unnecessary hysterectomy. Unnecessary hysterectomy gives a considerable sense of loss to the patient. If biopsy can distinguish uterine leiomyoma from uterine sarcoma, unnecessary surgery can be prevented.

The need for preoperative biopsy to prevent unnecessary surgery and prevent metastasis during biopsy is increasing.
